Water heating is a major energy consumer in commercial buildings, which is why they require systems that are reliable, efficient and able to meet varying levels of demand.

Representing the complete Noritz line of residential and commercial tankless water heaters and residential combination boilers, Keyline personnel will serve the entire plumbing and heating chain of distribution, calling on wholesalers, contractors, builders and inspectors, as well as mechanical and specifying engineers.

The new NPN will be offered in two series, the NPN-U (universal) and NPN-E (exterior), both of which will be available in 160,000 Btu/h, 180,000 Btu/h and 199,900 Btu/h models for either natural gas or liquid propane.

Unlike their traditional storage tank-based counterparts, tankless water heaters are capable of providing a constant flow of hot water on-demand. The concept is relatively simple: The heaters function by coupling a modulating burner with a high-efficiency heat exchanger.

This series achieves temperature stability of plus or minus 2° F through the active bypass, according to Bosch.

The EZ Series of high-efficiency, condensing tankless water heaters from Noritz America are designed to cut installation time and cost when replacing larger, storage tank-type units.

In the world of professional sports, few, if any, cities have seen as much change and exciting promise in the past 12 months as Las Vegas.

When helping homeowners choose between tank-type and tankless water heaters for a specific application, it’s advisable to get an impartial recommendation from a manufacturer that offers both technologies.
